ram

I need to launch Memtest86+ at startup of my Proxmox machine. I manage to add it to Grub, but then I don't know how to add it to systemd-boot. I do "proxmox-boot-tool refresh" and only available kernels are added, not Memtest86+. Any ideas?

Hello, first of all, sorry for my English as it is not my native language. I have a problem with some Proxmox servers and memory RAM. The sum of the memory of all the virtual machines diverges a lot from the total of the Proxmox server. All virtual machines have QEMU Guest Agent installed...

Hello, I have some problems with my PVE host and mostly with the RAM management. I attach the screen of my host resources: On this host, I installed one(and only one) VM, that it configured as shown in the following image: The Ballooning is corretly enabled, but I don’t understand why the...

Hello, I'm not sure if this is normal. PVE is reporting almost 50% RAM usage (out of 56 GiB) while all I have running are 2 lxc containers which combined have under 1 GB of RAM allocated. I do have a Windows 10 VM set up but it is stopped and its RAM is from 8 to 24 GB. When I use top to see...

Hey all, I normally use the host CPU option when setting up VMs (for best performance). This has worked great for me so far. I have recently setup another host server and set them up in a cluster. The new host has different hardware to the previous servers, so now I have Intel and AMD...

Hello everyone, Basically, I have a SuperMicro 1U with 128GBs of RAM installed. I just installed Proxmox fresh last night on it and it only ever registers 1.83GBs of RAM. The BIOS shows all four sticks populating and shows 128GBs, I tried swapping sticks in and out/different slots and nothing...

I have this weird issue where all of the VMs that I run, do not get the allocated amount of memory. When rebooting the VM, the correct amount of memory is in fact available in the VM, but after a couple hours, the maximum allowed memory in the VM will be way less. The issue is resolved when I...

Hi guys, Im running a ubuntu vm and allocated 15gb of ram to it, my server has 32gb total and is only using 60% at the moment. When I reboot the vm and run HTOP it shows all 15gb but after some time it go's to 1,64gb which causes issues like out of memory killer. Anyway to fix this? QEMU and...

Ich speichere meine Backups täglich auf eine extern eingebundene NAS. Das Problem ist, dass jedes mal, wenn meine Backups gemacht werden meine RAM usage in die Höhe schießt. Normalerweise ist sie bei 30% aber wenn die Backups laufen geht die usage bis auf 80% hoch. Merkwürdigerweise bleibt sie...

Hi, I've 16GB of RAM on my proxmox host and 1TB zfs root, with containers using approx. 70%/11GB of RAM: total used free shared buff/cache available Mem: 16366624 11155840 2862816 1282280 2347968 3578468 Swap: 0...

Hi. Continuing https://forum.proxmox.com/threads/windows-vm-memory-full-issues.90295/ thread as it was marked as solved but it's not actually. I have the same problem and the same picture in both Windows Task Manager and Proxmox GUI. VirtIO drivers including balloon seem to be installed: when...

Hello for everyone, I have an standalone node with 380 GB RAM and CPU usage is normal, 20 CT and 15 VM with Promox 6.3.6, I don't have IO delay. I just now I'm trying to configure a new CT, but I found that the container doesn't have SWAP memory (I did that setup with 2 Gb) so when I start to...

Hi, I have a VM that crashes every 10 days or so. I initially attributed the issue to something in Windows Server 2012R2. I wrote a little script to check status on this VM every 30 seconds, and restart it (and email me) if it crashes. The script just uses this: qm list|grep $VM_NAME |grep...

Hello, I just installed my Proxmox server. I have a strange phenomenon. The installation is brand new, I have no VMs started and I have constant ram usage at 18Go. Would this be normal behavior with ZFS using available ram to cache? If so, is it quite disturbing because we do not know how to...

Hi Am trying out Proxmox+ZFS on the same machine. Am new to ZFS. Am monitoring my server with Zabbix and my memory usage is 90%. It is of course mostly ZFS cache but how do I monitor when am running out of memory? Will ZFS always be at 90% so I can set my alarms at 95%? How do you guys monitor...

Hi, TL;DR : I'm trying to understand what the shared memory part of free means in proxmox I've recently created a new container on a host that reports a 60% memory usage I've got oom-kill that gets invoked because my RAM usage looks like that : total used...

I have a workstation with 256 GB RAM, and by default the host has only 8 GB SWAP. With the two LXCs I have, as they can potentially use a lot of RAM, I committed 192 GB RAM and 64 GB SWAP to both. My question is, in a situation where both LXC reaches a high usage and they consume more than 256...
